IDCompositionTranslateTransform::SetOffsetX(IDCompositionAnimation*) method (dcomp.h)
Animates the value of the OffsetX property of a 2D translation transform. The OffsetX property specifies the translation along the x-axis.
Syntax
HRESULT SetOffsetX(
[in] IDCompositionAnimation *animation
);
Parameters
[in] animation
Type: IDCompositionAnimation*
An animation object that determines how the value of the OffsetX property changes over time. This parameter must not be NULL.
Return value
Type: HRESULT
If the function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code. See DirectComposition Error Codes for a list of error codes.
Remarks
This method makes a copy of the specified animation. If the object referenced by the animation parameter is changed after calling this method, the change does not affect the OffsetX property unless this method is called again. If the OffsetX property was previously animated, calling this method replaces the previous animation with the new animation.
This method fails if animation is an invalid pointer or if it was not created by the same IDCompositionDevice interface as the affected visual. The interface cannot be a custom implementation; only interfaces created by Microsoft DirectComposition can be used with this method.
